Having fun with graphs, a short introduction to D3.jsMichael Hackstein
This talk is all about drawing on your webpage. We will have a short introduction to d3.js, a library to easily create SVGs in your webpage. Along the way we will render graphs using different layouting strategies. But what are the problems when displaying a graph? Just think of graphs having more vertices then you have pixels on your screen. Or what if you want a user to manupilate the graph and his changes being persistent? Michael will present his answers to this questions, ending up wit a GUI for a graph database.
Our favorite language is now powering everything from event-driven servers to robots to Git clients to 3D games. The JavaScript package ecosystem has quickly outpaced past that of most other languages, allowing our vibrant community to showcase their talent. The front-end framework war has been taken to the next level, with heavy-hitters like Ember and Angular ushering in the new generation of long-lived, component-based web apps. The extensible web movement, spearheaded by the newly-reformed W3C Technical Architecture Group, has promised to place JavaScript squarely at the foundation of the web platform. Now, the language improvements of ES6 are slowly but surely making their way into the mainstream— witness the recent interest in using generators for async programming. And all the while, whispers of ES7 features are starting to circulate…
JavaScript has grown up. Now it's time to see how far it can go.
In this presentation, I give an introduction to Windows PowerShell:
- What is it, and how does it work?
- How can you extend it to provide support for administering your own product or project?
NOTES:
1) Some of the text in this presentation is a little small for reading in a 400 pixel flash viewer. I'd recommend downloading the presentation instead.
2) The slides might not make sense without the notes that go with them. I've added the notes as comments to each slide. They still might not make much sense, but that's a different problem :-)
Advanced Analytics & Statistics with MongoDBJohn De Goes
Big data guru John A. De Goes, CTO of Precog, presents an overview of Quirrel, a high-level, statistically-oriented, open source query language designed for advanced analytics and statistics on large-scale JSON data sets. John discusses how the language can be used to solve a variety of common problems encountered by modern application developers, and then overviews ongoing efforts to port the language to MongoDB as part of a pure open source distribution.
Two years ago I inherited jsdom, a project of breathtaking scope. In essence, it aims to simulate a browser in JavaScript, by implementing JavaScript versions of a wide variety of web standards (much more than just the DOM). While maintaining jsdom for the last two years, and eventually bringing it to a 1.0 release, I learned an incredible amount about the web. I want to share with you what I’ve learned: the history of the standards and implementations of them that make up the web; the interaction between seemingly-disparate parts of the platform; and all about the strange APIs we’ve come to know and love. You should walk away from this talk with a new appreciation for how browsers work—and how, through the ongoing effort of a community of contributors and package maintainers, we’ve been able to recreate one in pure JavaScript.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
In his public lecture, Christian Timmerer provides insights into the fascinating history of video streaming, starting from its humble beginnings before YouTube to the groundbreaking technologies that now dominate platforms like Netflix and ORF ON. Timmerer also presents provocative contributions of his own that have significantly influenced the industry. He concludes by looking at future challenges and invites the audience to join in a discussion.
